[0021] The utility model provides an adjustable tunnel deformation monitoring device, such as Figure 1-3As shown, the adjustable tunnel deformation monitoring device includes: a tunnel inner wall 1 on which a support frame 2 is fixedly installed, and a slide groove is provided on the support frame 2; a monitoring box 3, and the monitoring box 3 is arranged on the support frame 2; a vertical pole 4, and the vertical pole 4 is slidably installed on the monitoring box 3 and extends to the outside of the monitoring box 3; a monitoring head 5, and the monitoring head 5 is fixedly installed on the vertical pole 4, and the monitoring head 5 is arranged corresponding to the tunnel inner wall 1; a fixing plate 6, and the fixing plate 6 is fixedly installed on the vertical pole 4, and the fixing plate 6 is in sliding contact with the monitoring box 3; a screw 7, and the screw 7 is rotatably installed in the monitoring box 3, and the screw 7 is threadedly connected to the fixing plate 6; a lifting motor 8, and the lifting motor 8 is fixedly installed in the monitoring box 3, and the output shaft of the lifting motor 8 is fixedly connected to the screw 7; an adjusting mechanism, and the adjusting mechanism is arranged on the fixing plate 6 for adjusting the angle of the monitoring head 5, and the adjusting mechanism is arranged corresponding to the vertical pole 4.

[0022] In this embodiment, the support frame 2 serves to stabilize the entire device, and the monitoring box 3 provides protection for the internal components and serves as a sliding track for the vertical pole 4. The vertical pole 4 realizes the lifting function by sliding on the monitoring box 3, thereby adapting to the monitoring needs of different heights. The monitoring head 5 is a core component, which is used to collect the deformation data of the tunnel in real time. The fixed plate 6 is threadedly connected to the screw rod 7, and the lifting and lowering adjustment of the vertical pole 4 and the monitoring head 5 is realized through the drive of the lifting motor 8. The adjustment mechanism is responsible for adjusting the angle of the monitoring head 5 to ensure that the monitoring head 5 can accurately align with the monitoring point and obtain comprehensive deformation data. The design of the adjustment mechanism enables the monitoring head 5 to flexibly adjust the angle to ensure the comprehensiveness and accuracy of the monitoring data.

[0023] In a further preferred embodiment of the utility model, the adjusting mechanism includes a first bevel gear 9, a rotating motor 10 and a second bevel gear 11, the first bevel gear 9 is fixedly mounted on the vertical pole 4, the rotating motor 10 is fixedly mounted on the fixed plate 6, the second bevel gear 11 is fixedly mounted on the output shaft of the rotating motor 10, and the second bevel gear 11 is meshed with the first bevel gear 9.

[0024] In this embodiment, the first bevel gear 9 is fixedly mounted on the vertical pole 4, and as part of the rotating component, it moves with the vertical pole 4. The rotating motor 10 is fixedly mounted on the fixed plate 6 to ensure its stability during the adjustment process. The second bevel gear 11 is meshed with the first bevel gear 9 to form a bevel gear transmission mechanism. This transmission method has the advantages of large transmission ratio, compact structure, high transmission efficiency, etc., and is particularly suitable for application scenarios that require precise angle adjustment. When the rotating motor 10 is started, it drives the second bevel gear 11 to rotate, and then drives the first bevel gear 9 meshed with it to rotate. Since the first bevel gear 9 is connected to the vertical pole 4, the vertical pole 4 and the monitoring head 5 thereon will also rotate accordingly to achieve angle adjustment. By adopting this bevel gear transmission mechanism, the adjustment mechanism can control the angle of the monitoring head 5 more accurately and stably, thereby improving the accuracy and reliability of the monitoring data.

[0025] In a further preferred embodiment of the present invention, a guide rod 12 is fixedly installed in the monitoring box 3 , and the guide rod 12 slides through the fixing plate 6 , and the guide rod 12 is correspondingly arranged with the screw rod 7 .

[0026] In this embodiment, the guide rod 12 is fixedly installed in the monitoring box 3 and slides through the fixed plate 6. This design allows the fixed plate 6 to be guided and restricted by the guide rod 12 during the lifting process along the screw rod 7, ensuring that it moves smoothly and accurately in the vertical direction, effectively preventing the fixed plate 6 from deflecting or shaking during the lifting process. The guide rod 12 and the screw rod 7 are arranged correspondingly, and together constitute a support and guide system for the lifting and lowering movement of the vertical pole 4 and the monitoring head 5, further improving the stability and reliability of the device.

[0027] In a further preferred embodiment of the utility model, a moving mechanism is provided on the monitoring box 3 for driving the monitoring box 3 to move, and the moving mechanism is arranged corresponding to the support frame 2. The moving mechanism includes two moving wheels 13, a dust cover 14 and a driving motor 15. The two moving wheels 13 are rotatably installed on the monitoring box 3, and the two moving wheels 13 are slidingly connected to the slide groove on the support frame 2. The dust cover 14 is fixedly installed in the monitoring box 3, and the dust cover 14 is arranged corresponding to any of the moving wheels 13. The driving motor 15 is fixedly installed in the dust cover 14, and the output shaft of the driving motor 15 is fixedly connected to the moving wheel 13.

[0028] In this embodiment, the mobile mechanism is arranged corresponding to the support frame 2, ensuring its stable installation and smooth movement on the inner wall of the tunnel. Two mobile wheels 13 are rotatably mounted on the monitoring box 3, and they are slidably connected to the slide groove on the support frame 2. This design enables the monitoring box 3 to move smoothly along the slide groove, thereby realizing deformation monitoring of different positions of the inner wall 1 of the entire tunnel. The function of the dust cover 14 is mainly to protect the drive motor 15 from dust and debris, ensuring its long-term stable operation. When the drive motor 15 is started, it drives the mobile wheel 13 to rotate through the output shaft, thereby driving the entire monitoring box 3 to move on the support frame 2. By adding a mobile mechanism, not only deformation monitoring of different positions in the tunnel is realized, but also the flexibility and convenience of the device are improved. The staff can move the monitoring box 3 by controlling the drive motor 15 as needed to achieve rapid positioning and monitoring of different monitoring points.

[0029] In a further preferred embodiment of the utility model, an energy box 16 is fixedly installed in the monitoring box 3 , and the energy box 16 is arranged corresponding to the monitoring head 5 .

[0030] In this embodiment, the main function of the energy box 16 is to provide a stable energy supply for the monitoring head 5 and other components that may require electricity. Since the monitoring head 5 needs to run continuously to collect deformation data of the tunnel, a stable energy supply is essential. The design of the energy box 16 takes this into consideration, ensuring that the monitoring head 5 can work stably for a long time.

[0031] In a further preferred embodiment of the utility model, a cleaning mechanism is provided on the monitoring box 3 for cleaning dust on the surface of the monitoring head 5, and the cleaning mechanism includes a fan 17, an air supply pipe 18 and an air nozzle 19, the fan 17 is fixedly mounted on the monitoring box 3, the air supply pipe 18 is fixedly mounted on the output end of the fan 17, the air supply pipe 18 is arranged corresponding to the monitoring head 5, there are multiple air nozzles 19, and the multiple air nozzles 19 are all fixedly mounted on the air supply pipe 18 and arranged corresponding to the monitoring head 5.

[0032] In this embodiment, the fan 17 is fixedly mounted on the monitoring box 3 to provide power for the entire cleaning mechanism. The air supply pipe 18 is fixedly mounted at the output end of the fan 17 to guide the airflow generated by the fan to the monitoring head 5. The air supply pipe 18 is arranged corresponding to the monitoring head 5 to ensure the accurate delivery of the airflow. The function of the air nozzle 19 is to blow the airflow in the air supply pipe 18 evenly and concentratedly to the surface of the monitoring head 5, thereby effectively removing the dust attached to the monitoring head 5. When the fan 17 is started, it will generate a strong airflow, which is transmitted to each air nozzle 19 through the air supply pipe 18 and blown out from the air nozzle 19, directly acting on the surface of the monitoring head 5. It can efficiently remove the dust on the monitoring head 5 and ensure the cleanliness and normal operation of the monitoring head 5. The cleaning mechanism can automatically clean the monitoring head 5 as needed, reducing the frequency and difficulty of manual maintenance and improving the automation and operation efficiency of the device.

[0033] In a further preferred embodiment of the utility model, a sensor 20 is fixedly installed on the monitoring box 3 for positioning the monitoring device, and a sensing element 21 is fixedly installed on the inner wall 1 of the tunnel.

[0034] In this embodiment, the sensor 20 is a high-precision sensing device that can sense the distance and positional relationship between the device and the inner wall of the tunnel in real time. By comparing with the pre-set position information, the current position of the device can be accurately determined, thereby ensuring that the monitoring head 5 can accurately align with the target monitoring point. The function of the sensing element 21 is to provide a signal source that interacts with the sensor 20, so that the sensor 20 can accurately sense the relative position between the device and the inner wall of the tunnel. Through the coordinated use of the sensor 20 and the sensing element 21, an accurate positioning function can be achieved, which not only improves the accuracy of the monitoring head 5 aligning with the target monitoring point, but also enhances the stability and reliability of the entire device. Through the preset path and position information, the device can automatically move to the designated position for monitoring, which greatly improves work efficiency and monitoring accuracy.

[0035] In summary, compared with related technologies, the adjustable tunnel deformation monitoring device of the utility model realizes efficient and accurate monitoring of tunnel deformation as a whole. By optimizing the adjustment mechanism, adding a mobile mechanism, installing an energy box, and introducing a cleaning mechanism and positioning function, the device can not only flexibly and stably monitor the inner wall of the tunnel at different angles and heights, but also automatically clean the monitoring head, ensure data accuracy, and achieve precise positioning to improve work efficiency.
